Answer:

Step-by-step explanation:

Let x be that number

The equation will be the following:

● (2/3)x - 11 = x + 4

Add 11 to both sides

● (2/3)x - 11 + 11 = x + 4 + 11

● (2/3)x = x + 15

Add -x to both sides

● (2/3)x - x = x + 15 - x

● 2x -3x/3 = 15

● -x/3 = 15

Multiply both sides by -3

● -x/3 × 3 = 15 × -3

● x = -45

If each angle in a decagon is the same measure, what is that measure? 18° 180° 144° 72°

pishuonlain [190]

Answer:

Each Angle of Decagon = 144 degrees

Step-by-step explanation:

The interior angles of a decagon add up to 1440

If they are of the same measure, then every angle will be equal to:

Each Angle of Decagon = 1440/10

Each Angle of Decagon = 144 degrees
